The gentle sway of the hammock, the rustling of leaves in the gentle breeze, the warmth of the sun on his face – Leo was in his element. The afternoon was pure bliss, a moment of tranquil perfection that he wanted to savour. He picked up his phone, finally feeling ready to start work on his next piece. The he saw a notification. Someone had tattooed his charcoal sketch of a lighthouse onto their ankle.

A broad, genuine grin spread across his features. He felt an inner glow, a warmth that radiated from his core. He’d never felt so validated. He felt like he could fly, or leap. He immediately responded to the message.
